Improvement in pumps

Letters Patent No. 92,373, dated .uly 6, 1869.

IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making prt of the same.

To whom it may concern Bc it known that I, CHRISTIAN SCHMIDT, of Rock Island, in the county of Rock Island, and'State of Illinois, have invented a new-and useful Double-Acting Pump.

I herewith give a full description of the same, the accompanying drawing forming part of the specifica tion.

Plate 1 represents a sectional drawing of my invention. l

A B C D represent a suitable framework.

V V, the ground-work.

F F, a fly-wheel. d

l I are two metallic washers secured in position; (collars.)

E E E, a shaft connecting the eccentric wheel k with the crank-combination b b, which 1n turn is connected with the piston z x.

S' S2 are sectional views of two piston-plates, which are connected with the shaft X X, and are supposed to be air-tight.

, L, a valve vwhich opens inward.

O, a valve which opens outward.

N, a valve which opens inward.

S a valve which opens outward.

Figures (i, 7, 8, and 9 represent the top and bottom plates ofthe double cylinders 1 and 2, and 3 and 4. The 'cylinders are joined in the centre at U U.

The arrows 10, 11, 12, and 13 point out two or more iron rods, passing through projecting flanges of top and bottom plates. The said plates are so constructed that the cylinders fit within those plates, and are securely held in position. The terminals of the binding-rods are provided with suitable binding-nuts or their equi-valents.

The tubes Rt, R, R2, R, are connected at c, and form the feed or supply-pipes of the pump, and S S are connected at lr, but either ofthe tubes described may be separated from the other, and so used.

The pump may be usedas two pumps (one for air and the other for water) at the same time.

l-lA is a pulley sccured on the shaft described, by means of which the double-acting pump may be worked by means of steam-power; or, by attaching a handle to the ily-wheel, as at NT, it may be worked by man-power.

OTA represents a cistern of water.

, Having described the. parts of my invention, I shall now set forth its mode of action.

When the piston is moved upward, the water or air, as may be, will move along the pipe It, R, and pass through the valve N, and fill the lower cylinder or chamber, while the air above plate S will be forced upward, passing through the openings ttof plate U U, (or partition,) filling the chamber under the upper piston-plate S. During the upward motion of the piston,

l the valves MM will be shut; consequently the airabove the valves M M will in like manner be removed upward,

and pass through the valve Ovby S c to T performing v the functions designed.

During the downward motion ofthe piston, thevalves l M M will open, while the valves Oand N will close. The water or air, as may be, will rush through the valve L,

lling the space between L and M M, while' the water in the lower chamber will be forced out through the valve S, by c' and T.

My invention will be found of great value for many practical purposes, as its construction renders it quite portable.

It can be taken apart with ease and readjusted in a few moments, by`having a series of holes in the flanges of top and bottom, agreeing with each other, and sayv about an inch apart. The cylinder may be readjusted by simply turning one of them round, thus enabling an operator to adjust his tubes to almost any condition required. y

What I claim, and desire to secure by Letters Patent, i s- The combination and arrangement of chambers 1, 2, and 3, 4, with partitions U U and S S2, induction and eduction-pipes R Rl and S S combined and operating substantially as described.

CHRISTIAN SCHMIDT.
